If you haven’t heard of FitBit, it’s a digital wristband company that creates products worn like watches to track activity and movement. Users track how many steps they’ve taken each day and set goals that the devices then remind them of throughout the day. They are essentially tools that aid in the process of getting healthier and moving more.
Now, FitBit is attempting to use the data it collects to help with diagnosis of sleep apnea and irregular heartbeat, or afibrillation. FitBit reports having over 105 billion hours of heart-rate data already and 6 billion nights’ worth of sleep data. This is all in addition to the 200 billion minutes of exercise tracking data collected.
